In the lineup, the Cortex-A720 serves as a successor to the A715 “middle” core responsible for handling most computing tasks. While it offers improved performance, ARM’s primary focus with the A720 is on power efficiency. ARM claims that the A720 is over 20 percent more power-efficient than its previous design. Chipmakers also have the option to utilize a smaller ‘entry’ version of the A720 to reduce costs or shrink the hardware footprint.
ARM’s attention to power efficiency extends to the Cortex-A520 efficiency core, which is primarily intended for low-demand background processing and other lightweight tasks. However, reports suggest that the A520 outperforms its predecessor, the A510, by eight percent while offering a remarkable 22 percent increase in efficiency. This improvement indicates that even casual smartphone users can expect extended battery life on their devices.
